Making Microrobots Move
Our group has recently demonstrated three distinct types of microrobots of progressively smaller size that are wirelessly powered and controlled by magnetic fields. For larger scale microrobots, from 1mm to 500 μm, we microassemble three dimensional devices that precisely respond to torques and forces generated by magnetic fields and field gradients. In the 500 μm to 200 μm range, we have devel...
متن کاملMaking Grass and Fur Move
Trimmed NURBS are the standard surface representation used in CAD/CAM systems and accurate visualization of trimmed NURBS models at interactive frame rates is of great interest for industry. To support modification and/or animation of such surfaces, a GPU-based trimming and tessellation algorithm has been developed recently. First, the NURBS is approximated with a bi-cubic hierarchy of Bézier p...
متن کاملPlant stress adaptations--making metabolism move.
Persistently sub-optimal environmental conditions constitute stress. Perception and signaling lead to protein expression changes, the activation of new biochemical pathways, and repression of others which are characteristic of the unstressed state. Protective metabolic adaptations alter physiological reactions of the whole plant. Paramount among the mechanisms are oxygen radical scavenging, mai...
متن کاملMaking the Move: A Mixed Research Integrative Review
The purpose of this mixed research integrative review is to determine factors that influence relocation transitions for older adults who are considering a move from independent living to supervised housing, such as assisted living, using the Theory of Planned Behavior as a conceptual guide. PubMED, CINAHL, and PsychInfo databases were queried using key words: relocation, transition, older adult...
متن کاملMaking Components Move: A Separation of Concerns Approach
We present a new calculus for mobile systems, the main feature of which is the separation between dynamic and topological aspects of distributed computations. Our calculus realises the following basic assumptions: (1) every computation executes in a uniquely determined location (2) processes modify the distributed structure by means of predefined operations, and (3) the underlying programming l...
